9 Claims. c1, 110- 86) a My invention relates to improvements in furnaces and hasparticular reference to a furnace base unit which may be used in connection with both square or round boilers of various sizes.

One of the primary objects of the invention is to provide a base unit for furnaces having removable and interchangeable side portions one of which may carry for instance an ash pit door while another one may be provided with supporting means for a stoker unit or gun-type oil burner.

The invention also resides'in novel means for supporting the upper sections of a boiler whether of the square or round type.

The invention also contemplates a unit as characterized which is simple and inexpensive in construction, easy to assemble, is highly eflicient in practical use and the parts ofwhich when assembled providing an enclosed ash-pit for accommodating an ash-receiving tub, there being a large door-controlled'opening through which the tub may be inserted or removed. J

Various other objects and advantages of the invention will be understood and appreciated by those skilled in the art upon reference to' the accompanying drawings which illustrate a now preferred example of the invention. It is to be understood, however, that my inventive concept is susceptible of other mechanical expressions Within the spirit and scope of the subject matter claimed hereinafter. In the drawings, wherein the same reference characters have been used to designate the same parts throughout the several views- Fig. 1 is a perspective View illustrating my base unit in connection with a square boiler and a hopper-type stoker;

Fig. 2 is another perspective view illustrating the base unit in connection-with a so-called round type boiler and in connection with a bin-fed stoker;

Fig. 3 is a perspective illustration of the removable base wallwith which the stoker unit of Fig. 2 is associated; Fig. 4 is an exploded perspective viewofthe base unit as employed for either square or round boilers;

Associated with the base and boiler unit of Fig. 1 a

ice

hopper-type stoker unit designated by numeral 17 and which includes the hopper 18 which is supported by legs 19 and discharges into the vertical box-form conduit 20.

It is to be understood that the stoker unit 17 is or may be of any standard construction and per se forms no part of myinvention. It-may be noted, however, that the stoker assembly 17 ofFig. 1 has the coal supply conduit 21 which communicates with the hopper-conduit 20, and has the driven conveyor (not shown)'therein for supply,- ing the coal tothe burnersuchas isshown as 32 inFig; 3, Numeral 22 indicates anfelectric n otor having the'belt driven connection .with' the pulley-'23 ,of a blower 23b which supplies air into the furnace base through .the pipe 21a. In the particularfstoker ofFig. 1 the screwconveyor (not shown) of the conduit 21 will be chain driven in well'known manner from the blower unit 23!) as indicated generally ,by reference character 23a.

Referring to Fig. 2 the round-type boiler unit is indicated by numeral 24 and'has vthe fire box door 25 and the rearwardly extended flue pipe 26. .The stoker unit of Fig. 2 has the screw conveyor-incorporating pipe 27 leading from a coal bin (not shown) which pipe 27 discharges into a subjacent right-angularly disposed conveyor-incorporating pipe 28 which is shown in Fig. 3 as carrying at its inner end andwithin the base section the conventional has the drive-motor 31 for the "pulley"29b oftheblower 29 which discharges air into the furnace base throughl the manifold "30." lhe conveyor pipe '28fhas an attaching flange 281i for'att achment'tjo onefjof the base sides as indicated in Fig- 3; The'lconveyor .o'fthe conduit is driven .from'theblower 29 by 'a' chain or the equivalent 29a and theconveyor of the pipe or con'du'it is driven from the earlier-mentioned conveyor Lby means of. gearing28b'all of which is standard.

Coming now to the novel base me 'ber 15 which is the subject of my invention, Figs. 4 and 5 showthe same as comprising the bottom plate 33 from the corners of which rise the angle-form posts 34 whose upper. ends are connected by angle-bars 35. The horizontal flanges 35a-of the angle-bars may provide the seating support for'the boiler section or unit 16, of Fig. 1 when the cross-sectional hsis shown in'Fig. 5 and the boiler. unit suchas 16 0124 supportedupon the plate 36 about the-central hole 37 therein.,;Plate 36 will'pre'ferably be welded or otherwise fastened to the horizontal angle bar flanges'35a.

The disclosures of Figs. 4, 5. and 6. indicate how the horizontal *angle bai flanges'SlSm of the base support'the boiler-sustaining plate 36 which acts, with such flanges 35a in the support of, either -a' round orysquare boiler such as 16 and'24. Y

- Referring to Fig.4 andalso to Figs. 5-9, inclusive, it will be noted that the side closure lplates 42, 43, 44, and 45 are interchangeable and "that each'has ma rrginal holes 50 which are adapted to register with holes.51 of the. posts 34 toadmit' of such plat'es being bolted'in place as indicated at 5-2 in 'Figs. 5-9, inclusive. Q When the closure plates are assembled ,an enclosed lash pit is 1 providedj for receiyingjthe tub 53 which is removable through the ash door controlled opening. Dust incident 7 p to ash removal is thus eliminated. The plate 42 is shown as having the usual ash-pit door' 46 Which is hinged tothe plate asindi'catedat 4 6a, the

free end of .the door having the usual latch for keeper element 47. V V V V I V The plate 43. is the one which carries the sto k er unit, or rather through which the {blower pipe and coal supply pipe extend. Thus, the closure p late 43' has a hole "48.

7 for the coal supply'conduit 2-8 of: or the coal sui ply'-conduit 2 1.;of Fig. v l and' 1the air admission opening 49 {or communication with the blower conduit or'niani- 7 fold 30 of Fig.2 or 21a of Fig. Theiother two plates d44iand945 complete the enclosure of thwbase.

It is to beame at when the walls 42,""43, 44 and l'f are'in place as shown in Figs, 5 -9, inclusive, the upper j ends ofsame over-liethe lower -port-ions of the angle "bars. 3'5 so as to reinforcethe' furnacesea tl The interchangeability of the walls oft-he base 15 is important because it admits of the stoker unit and ash door being located at selected onesof the four 'base sides so that available space in theregio'n of the furnace can be used to the best advantage. Thus, employment of my base best loca'tion for the stoker hopper (Fig. 'l) is at any one of the three sides. I say any one of three sides al- 7 though it is really four because the unit 15 will usually able on said flange members and having a central open- 5 ing -of a size and shape generally conforming to the in:
